mtd: nand: ecc-hamming: Drop/fix the kernel doc
Some functions should never have been exported (the ones prefixed by __*), in this case simply drop the documentation, we never want anybody to use this function from the outside. For the other functions, enhance the style. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/20200929230124.31491-14-miquel.raynal@bootlin.com
